11.2 Definitions and explanations

Term Explanation
Alarm Alarms are errors that compromise the accuracy of the results. An alarm is generated, for
example, when a measured value is outside the defined measuring range. Comings and
goings of an alarm are registered with time stamps in the associated error list. When an alarm
is no longer present, and is no longer current, it can be accepted and thus removed from the
error list.
Analysis is the mode in which the device carries out systematic inspections of gas and thus the normal
operating state.
Approval file is an enSuite file which contains different country-specific approvals and sets which approval
for the device is to apply. It lists the parameters that are specially protected, contains all fiscally
relevant AFBs and the text passage of approval.
Audit trail is a two part protocol archive (Parameter-change-archive) and gives the user the option of
payroll-relevant changes without opening the Security switch (SSW). These changes will be
monitored in the fiscal part and documented. The data can be viewed on the device screen
and copied with the help of enSuite. If SSW is open, only records in the general part are made.
Base Calibration Before a device is delivered, a base calibration with several gases has been performed by
Elster GmbH. If necessary, they will be performed again subject to readjustments by Elster.
Basic display is the name for a display which includes a composition of the most important results. Where
appropriate, there are further subordinate displays. The device starts with this display.
The Q2 Main display is the factory set basic display.
C2+
This number means that all higher hydrocarbons are collected to the ethane component.
